BACKGROUND ART

Ras is a 21 kDa protein which plays an important role in the events associated with cell growth and differentiation. It combines with guanine nucleotide, whereby catalyzes the hydrolysis reaction from guanosine triphosphate (GTP) to guanosine diphosphate (GDP). Further, this protein has been reported to act as a molecular switch regulating the specific GTPase cycle inside the cell (see: Bourne, H. R., Sanders, D. A., McCormick, F. Nature 1991, 349, 117).

The mammalian Ras protein is coded by three (3) types of ras gene and classified into four (4) types; i.e., K-Ras-4B consisting of 188 amino acid residues and H-Ras, K-Ras-4A and N-Ras consisting of 189 residues, respectively. Amino acids 12, 13 and 61 of Ras, positioned in the neighborhood of phosphoryl group of GTP, regulate the activity of GTPase by having a large effect on spacial position of a water molecule which participates in the GTP hydrolysis. In human cancers, mutations are observed at the above amino acid positions. Since Ras mutations inhibit its ability to regulate GTPase activity, GTP-binding state of Ras is maintained, and thus, growth signal is transduced abnormally to cause cancer. In particular, ras oncogene is related to pancreatic cancer, urinary bladder carcinoma, lung cancer and skin cancer, etc. (see: Bos, J. L., Cancer Res., 1989, 49, 4682).

To be in its biologically activated state, Ras must be attached to cell membrane and for this reason, modification or carboxyl terminus of the protein is required after the transportation of protein. The modification process comprises the steps of farnesylation of Ras by Ras farnesyl transferase, displacement of AAX peptide consisting of 3 amino acids at the C-terminus of Ras by peptide cleavage enzyme, methyl esterification of Ras by methyl transferase and palmitoylation of Ras by palmitoyl transferase. Among the above-described steps of modifying carboxyl terminus of Ras, the farnesylation step is proceeded by farnesyl transferase (FTase), and substrate for the transferase is CA₁A₂X peptide consisting of 4 amino acids at the C-terminus or Ras, where A₁ and A₂ are aliphatic amino acids having no charge and X is methionine, alanine or serine, etc. The farnesylation occurs at cysteine, and sulfur ether bond is formed. While, in H-Ras and N-Ras, palmitoylation occurs at another cysteine proximate to the C-terminus. The above-described farnesylation results in the enhancement of hydrophobicity of Ras, and hence its affinity for cell membrane increases. The farnesylated Ras is subjected to the cleavage of AAX peptide from the C-terminus thereof by the cleavage enzyme and methyl-esterified so that it can attach to the lipid layer of cell membrane or other receptors more easily. K-Ras-4B, differently from H-Ras or N-Ras, has a multiple lysine-arranged-region named polybasic domain, instead of having cysteine required for palmitoylation. It has been known that the polybasic domain facilitates Ras to bind to anionic lipid of cell membrane. All the above-described steps attribute to enhancing the attachment of Ras to cell membrane under the optimal condition, but only the farnesylation step is essentially required to express the biological activity of Ras. That is, if farnesylation step is inhibited, the resulting mutant Ras is prevented from being attached to cell membrane. Hence, inhibitors of farnesylation have been subjects of many studies (see: J. E. Buses et al., Chemistry & Biology, 1995, 2, 787).

As results of the studies, when farnesyl transferase is inhibited in a cell transformed by Ras, it is observed that the conditions of abnormal cells caused by mutant Ras are improved while growth of cells is inhibited.

Several inhibitors of farnesyl transferase are found to selectively inhibit intracellular prenyl group reaction of oncogenic Ras (see: Kohl, N. E. et al., Proc. Natl. Acad. Sci. USA, 91, 9141(1994); Kohl, N. E. et al., Nature Medicine, 1, 792(1995)). The inhibitors of farnesyl transferase being studied recently include peptide variants having cysteine thiol group imitating CAAX and improved inhibitors (see: U.S. Pat. No. 5,141,851; Kohl, N. E. et al., Science, 260, 1934(1993); Graham et al., PCT/US95/12224), peptides modified by phenyl group (see: Sebti, S. M., J. Biol. Chem., 270, 26802, 1995), variants using benzodiazepin, a frame structure of positive psycopharmaceuticals, as turn-imitating structure of peptide (see: James, G. L. et al., Science, 260, 1937, 1993) and inhibitors having tricyclic organic compound frame deviating its peptide structure (see: Bishop, W. R. et al., J. Biol. Chem., 270, 30611, 1995). In addition, a new type of inhibitor wherein (+) charge in the transition state is linked with the prenyl group has been reported. It was designed upon the notice that since the reaction mechanism in the transfer of prenyl group by farnesyl transferase is a type of electrophilic displacement, this reaction requires (+) charge in transition state (see: Poulter, C. D. et al., J. Am. Chem. Soc., 118, 8761, 1996).

However, the activation of K-Ras has been found in most human cancers, and most of the prenyl transferase inhibitors developed hitherto are found to activate K-Ras. The existing inhibitors inhibit the growth of cells transformed with K-Ras less effectively than that with H-Ras or N-Ras. Therefore, new inhibitor having the capability of effectively inhibiting K-Ras activity is required.

Thus, the present inventors established a new evaluation system by which the inhibitory activity against enzyme action for K-Ras substrate and inhibitory activity against intracellular K-Ras prenylation can be determined. Then, we synthesized novel compounds inhibiting the farnesylation of H-Ras, N-Ras as well as K-Ras and screened them using said new system. As a result, we have found that the compound of formula (1) as defined above can be used as an effective anti-cancer agent, etc., and then completed the present invention. Particularly, the compound according to the present invention has a characteristic structure different from those of the existing inhibitors against farnesyl transferase and does not include any thiol group.

Therefore, the object of the present invention is to provide the compound of formula (1) having a superior anti-cancer effect and process for preparation thereof.

It is another object of the present invention to provide compositions for treating cancer, restenosis, atherosclerosis and viral infections, respectively, each of which comprises as an active ingredient the compound of formula (1) together with the pharmaceutically acceptable carrier.

Specifically, Ras farnesyl transferase produced by genetic recombination techniques was used, and fused protein of H-Ras(H-Ras-CVLS) substituted with polybasic lysine domain at C-terminus of K-Ras (see: Korean Patent Appln. No. 97-14409) was used as a substrate after it had been purified according to the known method(see, Chung et al., Biochimica et Biophysica Acta, 1129, 278, 1992).

The enzyme reaction was performed in 50 μl of 50 mM Sodium HEPES buffer solution containing 25 mM of potassium chloride, 25 mM of magnesium chloride, 10 mM of DTT and 50 μM of zinc chloride. 1.5 μM of Ras substrate protein, 0.15 μM of tritium-farnesylpyrophosphate and 4.5 nM of farnesyl transferase were used. More specifically, in the initial step, farnesyl transferase was added to the above buffer solution, reaction was maintained for 30 minutes at 37° C. and then the reaction was stopped by adding 1 ml of ethanol solution containing 1M HCl. The formed precipitates were adsorbed to GF/B filter using Hopper harvestor(Hopper #FH 225V) for filter-binding, washed with ethanol, and then radioactivity of the dried filter was measured using LKB β counter. Enzyme titer was measured in the unsaturated state of substrate where the concentration of Ras substrate protein and farnesyl transferase have quantitative relationship. The compound according to the present invention dissolved in dimethyl sulfoxide(DMSO) was added to the reaction solution in an amount of less than 5% of the total reaction solution, and then the enzyme inhibitory activity thereof was measured. The enzyme inhibitory activity was represented by percentage of the amount of farnesyl incorporated into the Ras substrate protein in the presence of the test compound to that in the absence of the test compound. IC₅₀ of the test compound was defined as the concentration at which 50% of the enzyme activity was inhibited. To evaluate the selective enzyme inhibitory activity of the compound according to the present invention, inhibitory activity on geranylgeranyl transferase was measured. Geranylgeranyl transferase was purified from bovine brain according to the modified Schaber's method(Schaber et al., J. Biol. Chem. 265, 14701, 1990), and substantially the same experimental procedure as that for farnesyl transferase was performed on geranylgeranyl pyrophosphate and Ras-CVIL substrate protein. The test results are represented in the following Table 2.

The amount of radioisotope in the supernatant was measured and standardized to obtain a quantitative result in immunoprecipitation reaction and then, Y13-259, a monoclonal antiboby specifically binding to Ras protein(see: Furth, M. E. et al., J. Virol, 43, 294, 1982) was added and reacted for 15 hours at 4° C. Protein A(combined with goat anti-murine immunoglobulin antibody)-agarose suspension was added to the solution and reacted for 1 hour at 4° C. and then, to remove the unspecific binding product, immunoprecipitates were washed with a buffer solution (50 mM Tris chloride buffer solution containing 50 mM of sodium chloride, 0.5% of sodium dioxycholate, 0.5% of NP 40 and 0.1% of SDS). The precipitates were added to a buffer solution for electrophoresis and boiled and then, electrophoresis was performed using 13.5% of SDS polyacrylamide gel. After electrophoresis, the gel was fixed and dried. Then, the gel was exposed to X-ray film, developed and printed. From the result of the experiment, intensities of band of protein combined with or without farnesyl of Ras protein was measured, and the concentration of the test compound inhibiting 50% of farnesyl binding was defined as CIC₅₀, an in vivo Ras farnesyl transferase inhibitory activity.
